Specication of Letters Patent.

Patented Dec. 6, 1910.

Application filed November 24, 1909. Serial No. 529,783.

To all whom 'it may concern:

Be it known that I, GORDON LAND, a citizen of the UnitedStates of America, and a resident of the city of Seattle, in the county of King and State of Vashington, have invented certain new and useful Improvements in Valves, of which the following is a specication.

My invention has particular reference to valve shifting mechanism, and resides in a novel provision for connecting a valve stem and lever, as hereinafter set forth and dened in the appended claims.

In the accompanying drawing, wherein like reference numerals designate corresponding parts throughout: Figure l is a plan of a valve with my improved shifting mechanism applied thereto. Fig. 2 is a vertical section of the same. Fig. 8 is a perspective of the valve stem head with a portion thereof broken away, and Fig. 4 is a vertical section of a. valve of modied form, equipped with my improved shifting mechamsm.

I/Vhile both of the valves shown are adapted for use as intake valves in connection with flushing apparatus, such as Siphon flush tanks, my invention may be applied to valves of a different form, as will be readily understood from the following description.

In Figs. l and 2 I have shown levers 4 and 5 connected by a link 6 and fulcrumed respectively on lugs 7 and 8, provided on the valve body 9 at opposite sides of the stem 10 of valve l0.

Reference numeral 14 indicates the valve seat which is conveniently provided on a rel movable plug 15. Lever 4 extends in crosswise relation to stem l0 and is provided with an opening 40 which receives the stem freely and is suitably flared for clearance of the latter when the lever is moved to various angular positions. This opening extends between convexedge surfaces 4l which are provided on lever 4 for riding engagement with opposing bearing surfaces of a head 1l of the valve stem. Head 11 is provided with a suitable slot or opening which receives the adjacent portion of lever 4 snugly but freely, and in the top and bottom walls of this slot or opening, apertures, as l2, l2 are pro- I vided. Aperture l2 is screw threaded for engagement with corresponding screw threads provided on the valve stem, whereby the latl ter may be conveniently adjusted longitudinally with respect to the head. The base portion of head ll is preferably extended in the form of a bell, as clearly shown, to provide a deector over the passage-way 9', which leads from the seat of valve l0. Upward movement of lever 5, elevates stem l0 through the medium of link 6, lever 4 and head ll and thereby draws valve l0 toward its seat. The degree of such movement of lever 5 required to close the valve may be expeditiously regulated, as may be desired, by application of a wrench to the upper end portion of stem l0 to turn the latter in its seat in head l1, as will be readily understood.

The construction and arrangement of the shifting mechanism disclosed in Fig. 4, is identical to that just described excepting that lever 5 appears in connection with link 6 as a lever of the iirst order. By this arrangement, valve l0 will be drawn upwardly toward its seat upon downward movement of lever 5. Such movement of the lever is however, limited by a stop, as 13, provided in the path of lever 4. Valve l0 may therefore be adjusted by proper manipulation of stem 10a, to lie clear of its seat when lever 5 is lowered, as may be desired in using the valve as a ball cock or float valve in automatic Siphon flush tanks.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

l. In combination with a movable valve and the stem thereof, an operating means for said valve including alever formed with opposite convex surfaces and having an opening extending through the same and freely receiving said stem, and a connection between said valve stem and said lever comprising a head secured to said valve stem and provided with spaced bearing surfaces for riding engagement with the convex surfaces of said lever.

2. In combination with a movable valve and the stem thereof, an operating means for said valve including a lever formed with opposite convex surfaces and having an opening extending through the same and freely receiving said stem, and a connection between said valve and said lever comprising a head secured to said valve stem and formed with an opening through which said lever projects with its convex surfaces in riding engagement With the adj aeent opposite Walls thereof.

3. In combination with a movable valve and the stem thereof, a head adjustable on said valve stem formed with an opening, and an operating means for said valve including a lever projecting through the opening of said head and being free for angular movement therein.

4L. In combination with a movable valve and the stem thereof, a head on said stem having 'its lower portion enlarged to form a delector, and operating means for said valve including a lever having connection with said head.

5. In combination with a movable valve and the stem' thereof, said stem having anV free end portion, a head externally threaded formed with an opening pro-vided in its op-n Vjecting through and freely engaged in the opening of said head. y
